信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

这样的问题是你的页面中含有的注释去掉就好了，tomcat7.0.20.

tomcat 7对EL表达式的语法要求比较严格，例如"${owner.new}"因包含关键字new就会导致解析出错。
问题是出来了，怎么解决呢？有三种，如下：
第一种：严格遵守java规范，修改对象的属性名称，要求不包含java关键字;
第二种：修改EL表达式，例如"${owner.new}"可以修改为"${owner['new']}";
第三种：修改tomcat属性，忽略对EL表达式的关键字检查。修改$CATALINA_BASE/conf/catalina.properties文件，添加org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true选项。
